“The Essentials of Computer Organization and Architecture is an outstanding text that builds from the lowest level of logic gates through the circuits of the CPU up to the complexity of modern machines. I’ve used this text since 2008 (Second Edition). Each new edition has brought additional clarity to the material. One of my students said, at the end of the term, I feel like I could build a computer from scratch!” The exercises are well-designed so that I can assign problems that test the topics we’ve focused on. It is a vast, rich collection of information.” -Jacqueline A. Jones Associate Professor, Dept. of Computer and Information Science Brooklyn College of the City University of New York Updated and revised to reflect the most current data in the field, perennial bestseller The Essentials of Computer Organization and Architecture, Fourth Editionis comprehensive enough to address all necessary organization and architecture topics, but concise enough to be appropriate for a single-term course. Its focus on real-world examples and practical applications encourages students to develop a “big picture” understanding of how essential organization and architecture concepts are applied in the computing world. In addition to direct correlation with the ACM/IEEE CS2013 guidelines for computer organization and architecture, the text exposes readers to the inner workings of a modern digital computer through an integrated presentation of fundamental concepts and principles.
